Abstract :
In this research it has been discussed how new solutions can be used in order to provide visual comfort of students and decrease the energy consumption in educational buildings, because the educational buildings are used when daylight exists. For the importance of daylight in increasing the productivity and its impact on the health, convenience and increasing visual efficiency in learning, reading and writing, these buildings have necessarily been considered. The purpose of this article is to investigate the effect of the inclination angle of atrium on the daylight performance by parametric analysis while visual tranquility has been provided. For achieving to goal of this research, a primary school which has a diagonal atrium and is located in the northwest of Tehran was chosen as a case study. Different inclination angles of the atrium based on the orientation towards the solar diagram and its effect on the amount of daylight penetration at certain times in 3 adjacent classes to the atrium with inclination angles towards north- south were analyzed. The calculated results of the simulator software Radiance and Daysim, according to the subject of the regulations of lighting energy CIBSE(LG10 & Guide A ) (1999&2006) and school design CIBSE (2007), were analyzed and used. Eventually the field photometric examination by the use of an illumination tool (Data Logger) was utilized to compare and validate the analytical results and the findings of the analysis by software and thus the conclusion was presented .
